A motherboard can fail due to a combination of factors. Problems with the motherboard themselves are very common and typically don’t occur until after the warranty period. Heat, power spikes, humidity, and dust (in that order) are the enemies of motherboards.
By far the most common reason for failure is overheating. Sooner or later your motherboard will start to melt the solder connections and go out on you. The motherboard manufacturers do a good job of designing motherboards that will live longer than their warranty period under normal conditions.
The Main Causes for a Motherboard to die
This article will be discussing the 3 main causes for a motherboard to die:
- – Overheating,
- – Static electricity discharge
- – Power surge.
Overheating is probably the most common cause of a motherboard’s death. Generally, it occurs due to faulty cooling fans or improper ventilation in the case. You need at least one case fan in the front for intake and one or two fans in the back for exhaust. A good benchmark is to run a full system heat stress test (like Prime95, Linx, etc) for half an hour at least once every 6 months or so. Keep this up and your motherboard should be able to last a while before you have to replace it.
Static electricity discharge
Static electricity discharge can occur when you’re working on components inside of a computer such as installing new RAM, unplugging old RAM, replacing or upgrading parts, etc. Whatever the cause of static electricity build-up is, if you happen to touch any component with it then static can discharge all throughout your computer’s internal electrical circuit which may kill off some components like motherboards and hard drives.
Power surges are surprisingly common, but not as much as people think. Most surge protectors on the market offer a good amount of protection from power surges and spikes, so make sure you have one plugged in somewhere near your computer if it’s still plugged into an outlet. If you do get hit by a power surge then most likely damage will occur to your motherboard or hard drive(s). You can tell whether or not your motherboard has been fried by removing it from the case and checking for physical damages like burnt pins, melted plastic etc. If you notice any of these then it’s probably time to go out and buy a replacement motherboard because chances are no other component was damaged too badly besides that which you just removed.
However, if your motherboard still dies even after following these tips then chances are either one of the other components such as RAM, CPU, GPU, etc has also been damaged and they may have to be replaced too.
It is not that hard to keep your motherboard from dying. If you follow all three steps of “heat, static discharge, and power surges” then it should be able to last for a considerable amount of time. I know when my previous computer died (about 6 years ago) the reason why it was no longer working was most likely because either a motherboard or a hard drive had just died on me.
